JOSEPH FISHER AND JOHN GAMBLE, OF HARRISON, NEW JERSEY.

CURTAIN-ROLLER.

SPECIFICATION forming part of Letters Patent No. 225,582, dated March 16, 1880.

Application filed October 11, 1879.

as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawjugs, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to spring-rollers, the object of which is to secure a perfect balance between the spring and the curtain, thereby avoiding the use of a ratchet and pawl, and preventing the curtains from running up suddenly and rapidly, whereby they frequently get torn.

The invention consists in a spring curtainroll adapted to support a curtain or shade, having journals connected therewith or attached thereto out of the center, for the purpose of acting as a check when rolling up or unrolling the curtain and avoiding the necessity of a ratchet or pawl or gear of any kind, as will be hereinafter more definitely set forth and described.

-The general construction and arrangement of the parts are as follows: The spring is inclosed in a box attached to the end of the curtain-roll, one of its ends being secured to the side of said box and the other to a stem, which projects outward through the end of the same and constitutes a supporting-journal for the end of the roll, with which said spring is connected in the usual manner, but avoiding the use of a ratchet and paw], &c., as above stated.

In the accompanying drawings Figure l is a front elevation, showing a curtain and its roll with our improvements attached thereto. Fig. 2 represents the spring uncovered in its box and Fig. 3, which is partially in section, shows the journals out of the center of the roll.

Similar letters of reference indicate like parts wherever they occur.

A, Fig. 1, represents a curtain or shade; B,

Figs. 1 and 3, a shade-roll; and O a tube, at the end of which is formed a box, a, in which the spring 0 is located, oneend of said spring being secured to the box at a, Fig. 2, and the other end to the stem or journal 1), upon which the roll B revolves. Said tube 0, the outer end of which is closed, is intended to fit snugly on the end of the roll, and a box for the reception of the spring is formed therein by a partition, d. The spring 0 is made very flexible, and should be longer, by one-third or one-half, than the curtain which is to be held or raised thereby actually requires, the object of which is that by turning the journal to which the spring is secured, the latter may be shortcued or lengthened-that is, wound up or unwound,as the case may be--so as to secure the requisite balance between it and the curtain, as will be readily understood.

Having the journals away from the center, as indicated in Fig. 3, tends to prevent the curtain from going up or down of its own volition farther than it is guided by the hand;

hence so nice an adjustment of the balance between the curtain and spring as when the journals are in the center is not necessary.

The outer end of the stem or journal bis flattened or otherwise formed and adjusted in its bracket 6, so as not to turn therein, the journal on the opposite end of the roll being secured thereto rigidly, as indicated in Fig. 1.

Having thus described our invention, we do not claim, broadly, the application of the spring to a curtain-roll, as the same is not new; but

What we claim as new, and desire to secure by Letters Patent, is-

A curtain roll. adapted to support a curtain or shade, havin g journ als connected therewith or attached thereto out of the center, for the purpose set forth.

In testimony that we claim the foregoing we have hereunto set our hands this 2d day of October, 1879.
